Java Annotated Monthly - May 2020

Well April sucked. May isn't going to be much better, even if here in Spain they are actually letting us outside to exercise now. Hang on in there. Distract yourself with the articles in this month's newsletter if you like, or focus on other things that matter more. Take care of yourself and tho...

Java Annotated Monthly - April 2020

Well, what can I say? For much of the world it has been a terrible month (and let's be honest, we have not shown enough empathy for our friends in Asia who suffered this before us), and I'm not super optimistic about the next month or two. As usual, I'm compiling this newsletter from Spain, which...

Java Annotated Monthly - March 2020

It's only two weeks since the last Java Annotated Monthly and we have another huge issue! I'd like to say March's edition is dedicated to International Women's Day, and it can be if you like.

Java Annotated Monthly - February 2020

Holy guacamole there's a lot in February's Java Annotated Monthly! And it's not only because it's almost two weeks late! It's also because apparently I was either bored or stuck somewhere with just my phone and read a lot of stuff. Anyway now you have pages of things to read this Valentine's Day...
